This. invention relates to fastening-inserting machines and is herein illustrated as applied to a heel-end lasting machine having means for driving arow of tacks around the heel end of the bottom of a shoe to faste'ntheupper in "lasted 1 ent No. 2,059,241, granted on November 3, 1936 upon an application of mine, are provided witha row of tacking devices movable with the heel-end wipers for drivinga row of tacks around the heel seat to fasten the overwiped margin of the upper,

and with means for delivering the tacksto these devices from a plurality of raceways through tubes which leadrespectively to the difierent devices. In view of the large number oi'tacks which it is desirable to' drive in each shoe,'there are conveniently provided half as many raceways as tacking devices, a separator which receives two operative movements in each cycle of operations of the machine to separate two sets of tacks from the raceways, and a member which receives the two sets of tacksand delivers them .into theappropriate tubes. Each raceway thus supplies tacks to two of the tacking devices in the operation of the machine on each-shoe.

In operating on shoes of different sizes with a, machine of the above-mentioned character it -is desirableto vary thenumber of tacks driven-by example, the tack at each end of the row should beomitted, and in; operating on still smaller shoes it is desirable to dispense with two or three tacks at each end of the row. The construction herein shown is such that variation in the number of tacks driven may b'equickly and easily-effected. For'the purpose in view, tubes leading; to tacking devices which occupy analogous or corresponding positions at or near the opposite ends of the row of devices are arranged to receive-tacks supplied from the same raceway. That is, as herein illustrated, the tubes leading to thetwo devices at the opposite ends oi the row receive tacks from one raceway, the two devices next in line receive tacks-from another raceway, and the two devices which are third from the opposite ends of the row receive tacks from stillanother raceway. If it is desired, therefore, to omit the two tacks at the opposite ends-of the row, thisamay be accomplished simply by preventingdelivery of tacks additional raceways.

novel means for thus preventing delivery. of tacks, the construction shown comprising a plurality of raceway-closing 'fingers associated respectively In operating on some shoes; for

The above and other features of the invention. including various novel details of construction and combinations of parts, will now be-more particularly described with reference to the accompanying drawings and thereafter pointed out intheclaims. '1

The invention is herein illustratedas applied to a machine of the character fully disclosed in the above-mentioned Letters Patent, and only such parts of the machine therefore as it is necessary to refer to for an understanding of theinvention are hereinafter mentioned. The machineincludes a pairof wipers 2 (Figs. 1 and 5) which are movable lengthwise and laterally of the shoe to wipe the margin of the heel end of theupper inwardly over an insole on the last, the last and shoe being mounted on a-work support 4 and clamped about the heel end by a heel band 6. .Secured respectively to the different Wipers to move I therewith are two .tacker blocks 8 curved similarly to the wipers, these blocks cooperating with other parts to-provide arow of tacking .devices'for driving a row of tacks around the heel seat to fasten the overwiped margin of the upper in lasted position. Each tacking device, as illustrated in Fig. 5, comprises a spring-controlled finger in which cooperates with a flange l2 on the corresponding wiper 2 to provide a tack pocket in which a tack is supported in position to be driven through an opening M in the wiper, and a driver I6 for driving the tack, the several drivers associated with each wiper being fastened to a driver block l8 which is movable vertically in a guideway in the tacker block 8. The two driver blocks 11'8'81'8 operated by a member 20 connected to them in such manner as to permit them to move with the wipers.

The tacks are delivered to the tacking devices through a plurality of flexible tubes or conduits 22 which lead respectively to .the different 'devices, the lower ends of these tubes being mounted in openings in the tacker blocks 8. The tacks are supplied by "a plurality of inclined raeeways 24 from the lower ends of which they are 'separated and delivered by a reciprocatory separator 26. From the separator'the tacks fall into openings 28 in a removable end block 3! these openings communicating with other openings 32 pro vided in a raceway-supporting plate .34. Only one of the openings 28 and the opening 32 associated therewith are shown in the drawings, but it will be understood that a pair of such openings 28 and His provided for each raceway. In view of the largeinumber of tacks which it is desirable to drivein a machine of the character illustrated, it is preferable, as shown, to provide only half as many raceways as tacking devices, and accordingly the separator 26 receives two operative movements in each cycle of operations of the machine to separate two sets of tacks from the same raceways to be delivered respectively to different groups of tacking devices. In order to distribute the two sets of tacks to the proper tacking devices there is provided a reciprocatory receiving slide 36 which receives the tacks from the openings 32 in the plate 34 and delivers them into the proper tubes 22 through passageways 38 in a member 4!! to which the .upper ends of the tubes 22 are connected. The receiving slide 36 has, for each raceway, a pair of passageways 42 which, through movements of the slide, communicate successively with the corresponding opening 32 in the plate 3'4 to receive the two tacks delivered successively from the same raceway by the separator 25, thesepassageways being arranged to deliver the tacks into the appropriate passageways 38 in the member 40 and thus into the tubes 22 communicating with the passageways 38. The construction of the tack-supply.- ing mechanism as thus far described will be more fully understood by reference to United States Letters 'Paten'tNo. 1,933,594, granted on Novemher '7, 1933 upon 'an application of mine.

Lasting machines of the character illustrated are used to last shoes of 'difierent sizes, and it is accordingly desirable to vary the number of tacks driven by the machine. That is, in operating on some shoes it is desirable to omit the tack which would be driven by each of the two endmost tacking devices of the row of devices, and in lasting still smaller shoes two or three tacks at each end of the row should be omitted. As herein shown, therefore, the tack-delivering tubes 22 are so arranged that the two tubes [1. leading to the two endmost tacking devices, 1. e.,'the two devices located farthest from the extreme heel end of the shoe, are arranged to communicate at their upper ends with two passages 38 in the member 40 which are supplied with tacks from the same raceway, this raceway in the construction shown being the middle one of the group of eleven raceways. Similarly the two tubes 22 leading to the tacking devices next in line are, as illustrated, arranged to receive their tacks from the raceway nextat the right of the middle race way, and the two tubes 0 leading to' the devices which are third from the opposite ends of the row are arranged to receive tacks from the race way located next at the left of the middle raceway. Accordingly, if it is desired to omit the two tacks 'at the opposite ends of the row, this .may be done simply by preventing separation of tacks from themiddle raceway. The second tack from each end of the row, moreover, may be omitted by preventing separation of tacks from the raceway at the right of the middle raceway, and the two tacks which are third from the opposite'ends-of the row may be omitted by preventing separation "of tacks from the raceway at the left of the middle raceway. It will be understood that the machine might also include provision forsimi- 'larly'omittingadditional tacks, but in practice it has been found that there is ordinarily no necessity (for omitting more than the three tacks at each end of the row.

For conveniently preventing, when desired, the

separation of tacks from one or more of the three'above-mentioned raceways the construction herein shown comprises a modification of mechanism heretofore provided for preventing at will the delivery of tacks from all the raceways, so that the separator may be removed without releasing .the .rows of tacks, as disclosed in United .States Letters Patent No. 2,047,205, granted on July .14, 1936 upon an application of mine. In that mechanism, as in the mechanism herein shown, a shaft '44 extending transversely of the :raceways is supported by a fixed cover 46 mounted "over portions of the raceways and is rotatable about'the same axis as a movable cover 43 which, when in operative position, extends over the lower end portions of the raceways and over the sop 'arator 25, this movable cover being shown in Figs. 1 and 2 of the drawings in its upturned position. The "shaft 44 is rotatable by means of a small hand wheel 50 on one end thereof and has fast thereon, as heretofore, a plurality of raceway-closing fingers 52 associated respectively with all the raceways except, in the construction herein shown, those three from which tacks are supplied to the three pairs of tubes at, b and Thesha'ft extends through these fingers and they are permanently locked to it in alinement with one another by engagement with a fla face 5 3 (Fig. on the'shaft, the fingers being properly spaced from one another by collars 56 on the shaft. Accordingly, when the shaft is turned in one direction, with the cover 46 in its lowered position, these fingers are swung as a unit downwardly into the raceways and by engagement with the endmos't tacks move the several rows of tacks somewhat upwardly along the raceways and thereafter prevent any further delivery of tacks "from the raceways as long as the fingers remain in operative positions. For purposes of this invention there are associated with the raceways which supply tacks-to the tubes a, band c three fingers 58 which may be locked to the shaft M in 'alinement with the fingers 52 to move with the latter as heretofore when it is desired to close or open all the raceways, or may be unlocked from the shaft, each'independently of the others,

to permit one or more of them to be maintained in position to prevent delivery of tacks regardless of rotation of the shaft 44. Associated with each of these fingers at the right thereof is a spacing collar Sll'which, asdistinguished from each of the collars 56, has a reduced end portion upon which the finger is mounted, and slidingly movable in a guideway in each of these collars, alongthe fiat face 54 of the shaft, is a block 62 arranged to enter a correspondingly shaped opening in the finger 58 associated therewith to lock the finger to the shaft in alinement with the fingers 52. When the block is moved lengthwise of the shaft to withdraw it from the opening 64 in the finger, the finger may be swung'by the operator about its bearing on the collar 60 into position to enter the corresponding raceway andretractthe row of tacks. Each finger 58 has a lug dfi'thereon to assist the operator in swinging it out of the raceway when it is desired thereafter to open the raceway. Each block 62 is provided with 'a pin 68 extending through a slot 10 in the collar til for use in sliding it into or out of position to lock the finger which it controls in fixed relation to the shaft 44. Associated with each of the three fingers 58 is a resilient retaining member 'lz'secured to the fixed cover 46 and having a curved end portion arranged to enter a corresponding recess M in the finger to hold the latter in its operative position in the raceway. The member 12 also serves, by engagement with the finger in another recess 16 therein, to determine the proper position of the finger relatively to the shaftM for the block 62 to enter the recess 64 and lock the finger to the shaft when the shaft is positioned as determined by the cover 48 in the manner explained in Letters .Patent "No. 2,047,205.

A small plate, 18 fastenedon the'frontf of an angular plate 80 which is attached to the member 4! to support the upper ends of the tubes, 22 serves by means of arrows and the words First, Second and Third thereon to indicate where the upper ends of the pairs of tubes 11, b, and 0,

respectively, should be connected to the member 40 in assembling the parts, and preferably also these different pairs of tubes will be difierently colored to assist in tracing them, since it may be desired at times to detach one or more of them in case there is any obstruction to the delivery of tacks. The plate 18 serves also as a reminder to the operator of the relation of the three fingers 58 to the three pairs of tubes, so that he will know which finger to use to prevent delivery of tacks. to any particular pair.

It will be understood that when tacks are to be driven by all the tacking devices the three fingers 58 are locked to the shaft 44 in alinement with the fingers 52, so that by turning the shaft all the raceways may be closed, if desired, as heretofore. If the character of the work is such that the two endmost tacks of the row should be omitted, the operator releases the middle finger 58 from the shaft by sliding the appropriate block $2 to the right through engagement with its pin 58 while the cover 48 is in its normal position close above the lower end portions of the raceways, and then swings the finger downwardly until the retaining member 12 enters the recess 14 in the finger, thus closing the raceway which supplies tacks to the tubes a. Similarly the finger 58 at the right of the middle finger may be used, if desired, to prevent delivery of tacks to the tubes 1), and the finger at the left of the middle one may be'used to prevent delivery of tacks to the tubes 0. While any of the three fingers is in raceway-closing position it is not disturbed in any way by movement of the shaft 44, which may be turned, if desired, to close all the raceways not already closed and thereafter to open them again. When the operator wishes to open any raceway controlled by one of the fingers 58 heswings the finger upwardly by means of its lug 66 until the retaining member 72 enters the recess 16 and then locks the finger to the shaft by sliding the appropriate block 62 to the left.
